In Robert D. Kaplan's "In Europe's Shadow," the author explores how books reflect their owners' identities and values. When someone possesses a book for many years, it often carries not just personal memories but also deeper insights into their beliefs and priorities. This notion suggests that our choice of books can reveal aspects of ourselves that we might not consciously acknowledge or recognize.

The enduring presence of certain books in an individual's life raises intriguing questions about the connection between literature and personal experience. Rather than being mere possessions, these books become part of our narratives, showcasing our evolution and the particular experiences that have shaped our understanding of the world.
